1. The Battle of Honolulu took place on March 6, 1850. This conflict arose when a group of native Hawaiians led by Robert Wilcox attempted to overthrow the Hawaiian monarchy and establish a republic. The battle lasted only a few hours and resulted in the defeat and capture of Wilcox and his followers.

2. March 6, 1917, marked the official opening of the Hawaii Volcanoes National Park. This park is located on the Big Island of Hawaii and is home to two of the world's most active volcanoes: Kilauea and Mauna Loa. The park attracts millions of visitors each year who come to hike, camp, and witness the power of the planet's geology.

3. On March 6, 1959, Hawaii was admitted to the United States as the 50th state, ending a long struggle for statehood. It took over 60 years of lobbying, congressional hearings, and local support to achieve this goal. President Dwight D. Eisenhower signed the statehood proclamation, officially welcoming Hawaii into the union.

4. One of the deadliest tragedies in Hawaiian history occurred on March 6, 1946, when a tsunami struck the Hilo Bay area on the Big Island. The tsunami was triggered by an earthquake in the Aleutian Islands off the coast of Alaska and reached heights of 55 feet when it hit the shore. Over 160 people were killed, and entire neighborhoods were wiped out.

5. March 6 is also celebrated as "Prince Kuhio Day" in Hawaii, commemorating the birthday of Prince Jonah Kuhio Kalanianaole. He was a Hawaiian prince, statesman, and politician who played a key role in the creation of the Hawaiian Homes Commission Act of 1921, which provided land to native Hawaiians for farming and homesteading. He is remembered today as a champion of Hawaiian culture and sovereignty.
